The front end of the support pad 1 is provided with an air vent 2, and the metal frame 6 is set to an H shape.

[0033] Working principle: When the entire device needs to be installed, the support pad 1 can be placed on the front surface of the car seat first, and then the upper strap 41 and the lower strap 44 can be used to wrap around the car seat, and finally the buckle 42 and the sleeve 43 are plugged in, so that the support pad 1 can be fixed to the front end of the car seat.

[0034] When the support pillow 3 needs to be installed, the support pillow 3 can be directly placed at the front end of the support pad 1. At this time, the magnet 54 will be attracted by the metal frame 6 and move backward. The backward movement of the magnet 54 will drive the slide plate 53 to move synchronously. The backward movement of the slide plate 53 will drive the return spring 59 to stretch. At the same time, the slide plate 53 will drive the positioning block 55 to move backward by pushing the positioning spring 56. At this time, the simple fixation of the support pillow 3 has been achieved through the magnet 54. Then the fixing block 51 can be pushed inward to clamp the fixing block 51 on both sides of the support pad 1. When the fixing block 51 moves inward, it will squeeze the inclined surface of the positioning block 55 and force the positioning block 55 to move forward. After the fixing block 51 is clamped, the fixing block 51 can be released. At this time, the positioning spring 56 will push the positioning block 55 to insert it into the inside of the positioning groove 57 to fix the fixing block 51. At this time, the fixing block 51 will not be able to move outward, so that the support pillow 3 will be completely fixed. Even if the operator's body shakes, it cannot drive the support pillow 3 to deviate left and right.

[0035] When the support pillow 3 needs to be removed, you can directly put your palm into the gap between the support pillow 3 and the support pad 1, and then press the outer wall of the support pillow 3 forward to drive the slide plate 53 to move forward and reset. The slide plate 53 will drive the positioning block 55 to disengage from the inner wall of the positioning groove 57 by pulling the positioning spring 56. In this way, the operator can pull the fixing block 51 outward to release the fixation between the support pillow 3 and the support pad 1, and then the support pillow 3 can be removed.
